Abstract: The increasing complexity of the business processes requires automated methods for trouble-shooting and debugging of the process model in operation. This paper proposes mechanism of fault detection based on the concept of backwards reachability for the coloured workflow nets. The formal verification methods defined for coloured Petri nets such as state space method or place invariants declaration suffer from fast-growing computational complexity. The article offers the set of firing rules for backwards token-play on coloured workflow net. This method helps to detect resource-related failures of the two most common types: ”the missing arc” fault (the resource was not initialized) and ”wrong expression fault” (there is no proper resource).
